Mesoscale Parallel Experiment Change Log

Revert back to ops radial wind data due to 75-85% of
the Level 2.5 supob reports in /dcom/us007003/*/b006/xx002 having
a missing superob longitude (SUPLON) and a superob latitude (SUPLAT)
equal to 65.530 (for every report with a missing SUPLON). It
appears that something is corrupt in the incoming Level 2.5 raw
files from which SUPLAT and SUPLON are generated.

Ek, Mitchell

Added the effects of snow emissivity in the calculation of effective snow-ground
sfc temperature. This was done by changing the value from 1.0 to 0.9.

Ferrier

Modified the longwave and shortwave absorption coefficients for ice to be the same
as the operational eta.

Minor change in the order that solar zenith angle is called at the beginning
of the radiation driver.

Ferrier

Modified its configuration to be the same as what's running
in the EtaY, except that the cloud microphysics changes are removed - i.e.,
cloud droplet number concentrations are assumed to be 100 /cm**3 (an
autoconversion threshold of 0.419 g/m**3) and maximum ice particle
number concentrations are 10 per liter.

2004/11/18/12

Ferrier

Revert back to ops Eta values for the cloud water absorption
coefficients.

EDAS cycle started from ETAY control

2004/11/17/12

Ferrier

Reduced cloud water absorption coefficients by 25% from ETAY values
to permit slightly higher incoming solar radiation, to try to reduce cool/moist
bias in Eastern US and Alaska 2-m variables.
